Answer:
mixture
Explanation:
Chromatography is a process to separate the various substances present in mixtures based on their properties such as charges, size, affinity, etc. Â
A pure substance cannot be separated into various substances as it consists of a single type of substance only. A mixture consists of two or more substances that are separated by various physical and chemical methods. Â
The ink was separated into different colors on the chromatographic paper suggesting that it was a mixture of various colors. Therefore, the ink was a mixture, not a pure substance. Â
